API GH & KH General & Carbonate Hardness Test Kit for Freshwater Aquariums

Free Shipping at $75

The API Freshwater Hardness GH & KH Test Kit tests tap water and freshwater aquariums for general hardness (GH) and carbonate hardness (KH). Keeping these factors properly balanced creates a more healthy, natural environment for your freshwater aquarium fish.

  • General & carbonate hardness test kit
  • Monitor GH & KH to create a more natural habitat
  • For freshwater aquariums


The Freshwater Hardness GH & KH Test Kit helps detect stress on fish caused by rapid pH shifts, which result from low KH levels and helps aquarists duplicate the natural habitat of their fish.
